This is a difficult one as you may have already learned Parkinsons is a boutique disease, not the same for everyone.
My personal view is if you wish to try the' natural ' alternatives just check with your pd nurse or gp first. Lots of advice on diet and exercise on the net. You Tube PD Warrior, john pepper and his views on walking very fast as the best type of excercise, also plasticity where the brain can relearn tasks, improve movements with repetitive training etc.
There are ideas on inflammation and eating foods that reduce inflammation, coconut oil , just google away.
I am relunctant to recommend other than ensuring you are as healthy as you can be , excercise and a healthy diet.
PDUK site has some diet advice.
I am one of the ok to feel slower and take as few meds as possible gang, as diagnosed at 46 and now 56 so am mindful of side effects over the long term.
I know of others who take much more drugs to feel 'normal' , be able to keep their jobs etc.
It really is your choice and dependant on your circumstances.
You are not alone, many of us have this dilemna and for me a mix of drugs, vit D3, vit K2, Q10, B12 , magnesium and zinc. Stretching excercises , walking and getting rest when needed. Raspberries for fibre and vit C , reduction in red meat and increase in nuts, veg , look at research on inflammation not conclusive but may help.
I did not take meds/drugs for a year , then only 1mg rasagline in third year started ropinerole up to 8mg then reduced to 4mg last year. This year no ropinerole trying Sinemet levopda 25/100 3 times a day . Works for me but thats just me Ms slow coach.
Best of luck , x
